It has been just over one week now since I bought the GS. Since buying the bike last Saturday, I have already thrown some money at it, done some cleaning, tore some of it apart, reassembled most of those parts and I have literally bled on it. Yet, I have yet to try & start the motor.
Since buying the bike, I have gone through a variety of feelings about the project, pondering & even stressing over my choice… did I make a foolish choice, will it end up being a decent bike in the end, will all of the little things add up to putting way to much money into the bike, should I just part it out on eBay & make a little money? Showing pictures of the bike to some co-workers only added to my stress over my choice. They stated that all the little things will end up causing me to put more into it then the bike is worth. Which I do not feel that they are necessarily wrong, but at this point, I’m still going forward with the rebuild of the GS.
Upon further inspection since tearing into the bike, I have found more things then I first noticed… but this should not be abnormal for any project. So far, I have found:
- The front Master cylinder is dry, likely requiring me to replace the front master cylinder with the old brake fluid dried up inside of it.
- This will lead to possibly replacing the front brake caliper & brake line for the same reason.
- The rear brake does have old crappy fluid in it, but it doesn’t seem to be working, so that will need to be serviced with possible replacement parts needed.
- The air filter needs replacing, the foam was all gone, it’s just the metal cage of the filter that is left.
- The airbox needs a thorough cleaning, it is full of rust & flaky paint inside of it.
- The Chain is thoroughly rusted, so that’ll need to be replaced.
- Both tires are junk with weather cracks & just old-school scary technology.
- The gas tank has rust inside of it, I can hear it sliding around inside when I hold & shake the tank.
- The fork tubes are pitted up from rust, so I do not imagine that even new fork seals will last, that they will just be cut up from the pitting.

Yet, I am on the verge of testing the bike if it will pass Phase 1. Phase 1 is to just try & get the motor to run… this does not mean riding the bike. Tomorrow night, I hope to try & fire it up for the first time! I’m mixed with both excitement & nervous feelings. The way that I see it as of now, if the bike doesn’t run & I determine that it will take a lot of money to get the motor running, then the bike will fail Phase 1, & then most likely just be parted out to get my money back out of it. If I do get the bike to run, then it of course has passed Phase 1. Phase 2 will be to get the bike Safe & Legal for the road.

Well let me back up here for a moment… let me explain what I have done so far to get to be on the verge of trying to start the bike for the first time. As I mentioned in my first post of The GS Project, I did not want to try & start the bike with the rust in the tank, or the gummed up carburetors.
- Initially I put a new battery in it.
- Changed the spark plugs.
- Changed the oil & oil filter.
- Upon doing that, that is when I discovered that the tank has rust inside of it, so after asking around, I found out of a place here in town that treats the inside of gas tanks for this. They clean it out the best that they can, then they coat the inside with this rubber pigmented product. They claim that the tank will never rust inside again. Since I had three people tell me that they have had good results with this, I went for it. So the next day i get my tank back & it has this red color inside of it now. So that should take care of the tank.
- Next up was rebuilding the gummed up carbs. After taking them out & tearing them apart, wow! were they nasty! No wonder the throttle stuck & also no wonder the bike hadn’t started the last couple of times chuck tried to get it running. So after soaking the carbs in solvent & cleaning them, I then installed new jets, gaskets & etc with 4 carb repair kits that I purchased. My thoughts are that if the whole GS Project tanks… I should be able to sell the carbs on eBay & get some of my money back right there.

So far I have done enough that I feel I can put some new gas in it & try to fire it up. The motor should now be able to receive fresh & clean gas & air. I still have yet to clean/restore the airbox & also buy an air filter… but I’ll just try to fire it up w/o any filter or airbox on it, I don’t see that as an issue since I’ll only be revving it in my garage & not riding it. Maybe it’ll lean out the jetting a bit, but it shouldn’t be enough to prevent it from running.
Tomorrow night, I hope for the best. I’m anxious to hear how it even sounds. My expectations are for it to be a loud motor, with a lot of valve train noise & an exhaust that is old-school & a little loud… plus a slow rever. My previous street bike experience is from modern liquid cooled sport bikes 20 years newer then this bike.
